One of the sites that we finished up recently was Martini Park (no relation). Before you start gushing over its smooth look, I have to mention that CoolBirth was responsible for the graphics, base HTML, and CSS. Our business was to hook them up with a very custom CMS.
The CMS provides them with the ability to spawn sub-sites based on a master template. This lets them create new sites at will, all managed within the CMS, yet still be able make each individual site unique. They can create location specific galleries and events as well as items that appear across all sites. All this through one simple unified interface, not your typical Swiss Army Knife that can do everything but nothing really well. Have you ever tried to cut with one of those?
